Description
Bei den -bisher bekannten Flaschenzügen mit kreisenden Rädern besteilt der Übelstand, daß die Lagerung der Aatriebspindel und ider Kettennuß zueinander den Nadhteil hat, daß bei Lockerung des durch Stehbolzen zusammengehaltenen Gehäuses einerseits uind durch Verschleiß im Getriebe und in der Lagerung anderseits das Getriebe und die Bremse ungünstig beeinflußt wird.In the case of the previously known pulley blocks with rotating wheels, the disadvantage is that the storage of the drive spindle and ider chain sprocket to each other has the need part that with loosening of the housing held together by studs on the one hand uind through Wear in the gearbox and in the storage on the other hand, the gearbox and the brake are unfavorable being affected.
ίο Bei dem Erfindungsgegenstand besteht das den Haken aufnehmende Traggehäuse aus einem einzigen starren Stück. An dieses zentriert sich ein Abschlüßdeckel, der im Innern einen Zahnkran trägt. Es entsteht dadurch eine in sich unverschiebbare Bauart, die Klemmungen in den Lagerstellen und schädliche Beeinflussung der beweglichen Teile ausschließt.ίο The subject matter of the invention exists the hook receiving support housing made of a single rigid piece. Centered on this a cover that carries a gear crane inside. It arises from it an inherently immovable design, the clamps in the bearings and harmful influence on moving parts excludes.
Auf der Zeichnung ist der Gegenstand derOn the drawing the subject is the
ao Erfindung durch einen Längsschnitt dargestellt. Es bezeichnet 1 und 2 die Gehäusehälften, die je einen hohlen Lagerzapfen 3 und 4 tragen. Außen dienen diese Zapfen zur Lagerung der Kettennuß und der Lagerscheibe für die kreisenden Räder. In ihrem Innern bilden sie die Lagerung für die Antriebswelle 11.ao invention represented by a longitudinal section. It denotes 1 and 2 the housing halves, each of which has a hollow bearing pin 3 and 4. On the outside, these pins are used to support the chain sprocket and the bearing washer for the spinning wheels. Inside they form the bearing for the drive shaft 11.
• Zwischen Kettennuß und Lagerscheibe sitzen auf den an diesen Teilen befestigten Lagerbolzen 10 die Triebräder 8. In diese greift beiderseitig das auf der Antriebswelle 11 sitzende Ritzel. Die Triebräder wälzen sich in dem feststehenden Zahnkranz ab und bringen dadurch die Kettennuß in Umdrehung.• Between the chain sprocket and the bearing washer sit on the bearing bolts attached to these parts 10 the drive wheels 8. The one on the drive shaft 11 engages in these on both sides Pinion. The drive wheels roll in the fixed ring gear and bring thereby the chain sprocket in rotation.
Dadurch, daß die Lagerzapfen 3 und 4 außen die Lagerung für die Kettennuß 9 und die Lagerschei.be für die kreisenden Triebräder 8 bilden und gleichzeitig im Innern als Lagerung für die Antriebswelle 11 dienen, wird außerdem gegenüber den bekannten Bauarten erreicht, daß die Antriebswelle, die Bremse und das Getriebe von einem Verschleiß der übrigen Teile nicht berührt, die Arbeitsweise des Flaschenzuges, also nicht ungünstig beeinflußt wird.The fact that the bearing pin 3 and 4 outside the storage for the chain sprocket 9 and Form the Lagerschei.be for the rotating drive wheels 8 and at the same time inside serve as a storage for the drive shaft 11, is also compared to the known types achieves that the drive shaft, the brake and the transmission from wear the other parts are not affected, the functioning of the pulley system, so not unfavorable being affected.
